Guidelines for Chemically Stabilizing Problematic Soils

This project established protocols to help evaluate the utilization of chemical stabilization methods to potentially improve the engineering behavior of problematic soils with and without soluble sulfates within the state of Montana. In addition, construction life cycle cost analyses were used to compare existing approaches used by MDT versus chemical stabilization alternatives for problematic soils. The additional resources and time required to incorporate chemical stabilization were not included in the life cycle cost analysis.
